This reverts our previous CGO_ENABLED change: c1d3e9e814
It was causing depaware problems and is no longer necessary it seems? Upstream cmd/go is static nowadays.
And pulls in:
[release-branch.go1.24] doc/godebug: mention GODEBUG=fips140
[release-branch.go1.24] cmd/compile: avoid infinite recursion when inlining closures
[release-branch.go1.24] syscall: don't truncate newly created files on Windows
[release-branch.go1.24] runtime: fix usleep on s390x/linux
[release-branch.go1.24] runtime: add some linknames back for `github.com/bytedance/sonic`
Of those, really the only the 2nd and 3rd might affect us.

ShardedInt provides an int type expvar.Var that supports more efficient
writes at high frequencies (one order of magnigude on an M1 Max, much
more on NUMA systems).
There are two implementations of ShardValue, one that abuses sync.Pool
that will work on current public Go versions, and one that takes a
dependency on a runtime.TailscaleP function exposed in Tailscale's Go
fork. The sync.Pool variant has about 10x the throughput of a single
atomic integer on an M1 Max, and the runtime.TailscaleP variant is about
10x faster than the sync.Pool variant.
Neither variant have perfect distribution, or perfectly always avoid
cross-CPU sharing, as there is no locking or affinity to ensure that the
time of yield is on the same core as the time of core biasing, but in
the average case the distributions are enough to provide substantially
better performance.
See golang/go#18802 for a related upstream proposal.

For https://github.com/tailscale/go/pull/108 so we can depend on it in
other repos. (This repo can't yet use it; we permit building
tailscale/tailscale with the latest stock Go release) But that will be
in Go 1.24. We're just impatient elsewhere and would like it in the
control plane code earlier.

Update go.toolchain.rev for https://github.com/tailscale/go/pull/104 and
add a test that, when using the tailscale_go build tag, we use the
right Go toolchain.
We'll crank up the strictness in later commits.

Bump the Go toolchain to the latest to pick up changes required to not crash on Android 9/10.

This removes the unsafe/linkname and only uses the standard library.
It's a bit slower, for now, but https://go.dev/cl/518336 should get us
back.
